Delay when using android.speech.SpeechRecognizer in DICTATION_MODE

Question

I'm using android.speech.SpeechRecognizer in DICTATION_MODE to recognize commands during a long period of time. In this mode the call to the callback method onPartialResults delays much more than in normal mode. Does anybody know why this happen and how to avoid this delay?

This is the configuration I use for the SpeechRecognizer:

Intent recognizerIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);  recognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM); recognizerIntent.putExtra("calling_package", mainActivity.getApplicationContext().getPackageName()); recognizerIntent.putExtra("android.speech.extra.DICTATION_MODE", true); recognizerIntent.putExtra(RecognizerIntent.EXTRA_PARTIAL_RESULTS, true); recognizerIntent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 100); 

Answer 1

The problem may be because of the internet speed.

Try to set EXTRA_PREFER_OFFLINE to true and check whether the delay will be reduced
